In a parallel universe the heroic exploits of Garfield, Odie, Nermal, and Arlene are the stuff of legend, but even they may be no match for the diabolical comic book demoness named Vetrix. Vetrix has hatched a plan to make everyone in cartoon world her slaves, and with an army of zombies to do her bidding, she just might succeed. One minute, Garfield and friends are enjoying a sun soaked cookout, and the next they're doing battle with a malevolent alien and her mindless zombie minions. In order to defeat Vetrix, all the comic strip characters will have to become superheroes. Sure Garfield would rather be cooking out, but when he finally realizes just what's at stake, odds are good he'll rise to the challenge.
